NDSF (Non Dispersion-Shifted Fiber) The earliest type of single-mode fiber (SMF). NDSF improved considerably on multimode fiber (MMF) with respect to distance limitations. However, chromatic dispersion and material dispersion were discovered to be issues. NDSF runs in the O-Band, specifically in the 1,300–1320 nm range, where the effects of material dispersion are lowest in a standard single-mode fiber. Dispersion-shifted fiber (DSF) shifts the optimal dispersion point. See also dispersion, chromatic dispersion, DSF, material dispersion, MMF, O-Band, SMF, and window. |
